Managing File Copies   «Prev  Next»

Lesson 1

Creating and Managing File Copies

In this module, you will put your understanding of Oracle Recovery Manager (RMAN) to work and use it to create and manage physical file copies. By the end of this module, you will be able to:
  1. Perform online and offline backups
  2. Describe backup sets versus image copies
  3. Identify the use of channels with backup operations
  4. Recognize the use of tags and backups
  5. Create an image copy
  6. Identify why and how to parallelize the creation of image copies
  7. Use the operating system to create image copies

With this knowledge, you will be able to back up your system using file copies-one of two methods of implementing a backup strategy.

Description of the RMAN diagram above

The following elements are present in the picture:
Oracle Recovery Manager (RMAN): RMAN is a built-in backup and recovery tool for Oracle databases. It provides a comprehensive set of features for backing up, restoring, and recovering databases.
RMAN communicates with 1) Target Database and 2) Recovery Catalog

Oracle Enterprise Manager (OEM): OEM is a suite of tools for managing and monitoring Oracle databases. It provides a centralized console for managing database backups, recoveries, performance, and other tasks.

  1. Oracle Secure Backup (OSB): OSB is a cloud-based backup and recovery service for Oracle databases. It provides a secure and reliable way to back up and recover databases to the cloud.
  2. Oracle Cloud: Oracle Cloud is a suite of cloud computing services that includes Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) offerings. Oracle Cloud can be used to host Oracle databases, as well as other applications and data.
  3. Fast Recovery Area (FRA): The FRA is a dedicated disk area that is used to store backup files and other recovery-related data. The FRA is used by RMAN to perform backups and recoveries.
In the next lesson, you will learn about the two basic types of file backup, offline backup and online backup.
